IMPROVEMENT lN AXLE-BOXES AND SLEEVES.

Specification forming part of Letters Patent No.159,240, dated January 26, 187E application filed September 18, 1874.

To all whom it may concern Be it known that I, J. B. WINGHELL, of Benton Harbor, in the county of Berrien and State of Michigan,-have invented certain new and useful Improvements in Axles and Pipe- Boxes; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in axles and pipe-boxes; and it consists in the arrangement and combination of parts,wl1ich will be more fully described hereafter, whereby all dirt and gritty substances are prevented from getting in the pipe and lodging upon the axle.

The accompanying drawings represent my invention.

a represents a hollow iron axle-thimble, which has a screw-thread out upon its outer end to receive the nut 0, which holds the wheel in position upon the axle. Upon this thimble is formed the flange, (1, against which the inner side of the hub bears. Upon the under side of this thimble, extending inward from the flange, is the scraper e, which, as the hub revolves around, scrapes all the dust and dirt loose from the inner end of the box g, which, if allowed to remain there, would work its way in between the box and axle. The inner end of the thimble is made oval in shape, so as to receive as thick an end of the wooden axle as possible, and so that the greatest thickness of the axle will be in a line with the transverse strain brought to bear upon it. gis the box, provided with the projections 13, which prevent it from turning in the hub, and which projects over the sides of the nut 0, so as to form a protection at this point against dirt and dust. At its inner end it also projects over beyond the flange d to some distance, and formsa guard at this point also, to prevent the dirt and sand from working in, the scraper 6 serving to clean out the mud and dust at this point as fast as it gets in. Upon the top of the axle or thimble, back of the flange d, is a rise, j, which forms a vertical shoulder at its outer end, Which shoulder comes up almost close enough to touch the inner end of the box, and thus serves to prevent the greater part of the mud which is splashed upon the axle from getting inside of the box. Around the box, near its outer end, are made a number of triangular grooves, 1, in which the wood of the hub settles as the box is forced in position, so as to cause the box to be held more firmly in place.

Having thus described my invention, I claim- 1. The box 9, having its inner end projecting beyond the flange d, in combination with the rise j and scraper e on the thimble, substantially as set forth.

2. The scraper e, in combination with the box g, having its inner end projecting over the flange d to form a guard, substantially as specified.

3. The scraper e on the under side of thimble a, substantially as and for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand this 14th day of September, 1874..

JAMES B. WINOHELL.
